Apple today released watchOS 5.1.2 to all supported Apple Watch owners. The new software can be installed by heading over to the Apple Watch app on your iPhone. From there, access the Software update section and hit “Download and install” under the listing. You’ll need to have your Apple Watch on the charging puck to install the new beta to ensure you don’t run out of juice during the process.
With watchOS 5.1.2, Apple enables the EKG features aboard the Apple Watch Series 4 thanks to a new app. To take an EKG (via The Verge), open the app and set your index finger on the Digital Crown for 30 seconds. Your Watch will then record your heart information and store it in the Health app. From there, you can create a PDF of the information and send it to your doctor.
In addition, for all Apple Watches going back to the Series 1, watchOS will alert you of irregular heartbeat over the course of around half a day. Those with atrial fibrillation are advised not to use this feature, but it could come in handy for others concerned about their health.
Of course, these features come with the usual disclaimer that your Apple Watch can’t be used to diagnose yourself and won’t act like a doctor. It’ll advise you to visit a doctor if it detects irregular bodily behavior, but that’s it.
As always, watchOS 5.1.2 also comes with bug fixes and stability improvements.
